Letters Patent No. 87,494, dated March 2, 1869; mttedoted February 20,1869.

The Schedule referred to in there` Letters Patent and making past of thesame.

To allfwhom it may concern:

Beit knownthat I', WILLIAM H.'H1iNDERs0N, of Franklin, iu the county ofJohnson, and in the State of Indiana, have invented certain new anduseful Improvements in Device for Holding Tin Cans while Soldering; anddo hereby declare that the following is a full, clear7 and exactdescription thereof, reference being made to the accompanying drawings,and to the lettersof reference marked thereon.

The nature of my invention consists in the con struction of a hollowcone of sheet-metal, with its sides fastened together with an elasticspring, in such a Vmanner that, when its sides are pressed outward fromthe inside by a smaller cone, they will be permitted to expand, thissmaller cone being worked up or down, as may be desired, by means of ascrew, fastened to the top thereof, and passing through the tcp of thelarger or outside cone, and a nut or female'screw moving the same fromthe outside. A spiral-l spring around the screw, between the top of thesmaller cone and theoin'side of the larger, holds the smaller cone downin proper posi tion.

My invention also consists in theconstruction of a clamp, fastened on anarm extending from the-side ofVA the outside or larger cone, whichserves to hold the sides of a can together while being soldered.

To enable others skilled in the art to make and use my invention, I willnow proceed to .describe its con7 struction and operation.

In the annexed drawings, forming part o f this speci. o tion.-

represents a hollow cone, the top of which is flat, with a hole in it,to allow the screw B to pass through. Inside this cone A is a smallercone, C, to thetop of which the screw B is fastened. l This screw isworked by means oftliespiral spring D and nut E.

By turning the nut E, the inner cone C is raised up, and presses out thesides of cone A, which ris made to give, by means of an elastic spring,F, that fastens it together. This is for the purpose of springing thebottom of the can on.

On the side of the cone A is fastened a clamp, G,

lwhich is to hold theside seams together, by means of the eccentriclever H and* spiral spring'l, while the process of soldering isgoing'on. e

K represents the can, iixed on the machine.

The operation is as follows:

Set the body of the tin can in the bottom; then put the conical pressinto the body, observing to have the clamp on the same; screw downmoderately tight; then close the lever, and the can is ready to besoldered.

In using the `llanged bottom, the side seam only is soldered, Aafterwhich" the vessel is withdrawn, and the bottom set down with the commonmachine used by tinners for this purpose.

The advantage of this device is not only in facilitating the making ofvessels of tin and other materials, but also in adding greatly to thedegree of pew fection thereof,

Having thus fully described my invention,

What I claim as new, 'and desire to secure Aby Letters Patent, is

The combination of the elongated cone A and its spring F with thelinterior cone C, its screw'B, spring D, and the clamp' G and cam-leverH, all constructed and operating substantially as herein set forth.

`In testimony that I claim the foregoing, I have here-- unto set myhand, this 9th day of April,`18.68.

' WILLIAM H. HENDERSON.
